White spruce is a natural antihistamine provides relief from congestion, runny nose, and itchy eyes. Apply one or two drops to the top of each foot. Or put a drop in each palm, rub your hands together, and cup them over your nose and mouth.
Black spruce helps repair damage caused by sleeplessness, providing a boost to the adrenal glands. When your energy is dragging, put four or five drops in each palm, cup your hands over your nose and mouth, and breathe in deep.
